Review on 🐠 Two Little Fishies ATLAS3B Aquastik: The Ultimate 4-Ounce Grey Aquarium Adhesive by Sharon Weaver

I guess it depends what you use it for. I used it to attach two pieces of dry reef rock to the outside of the tank. They stayed well together. I then tried to use it to attach the shards to a piece of rock under water. The problem is that most corals like water flow. It didn't work well enough to stay in place even in light traffic. He just blasted the pieces off the rock. So I did the same in the area with no flow. When I threw the rock back into the stream a few hours later, it blew the pieces off the rock. Maybe I should have waited a day to reset it, but corals hate being moved. I think I'll start using other glue-free alternatives like plastic rods and zip ties. Or I'll try gluing the splinter to a piece of dry rock outside the tank and then placing it on a low stream. But it's just not the solution I was looking for.
